NOZZLE.

Specification of Letters Patent.

' Patented May 4, 1909.

Be it known that-I, WILLIAM G. HUGHES, a citizenof the United States, residing at Los in the county of Los Angeles and Stateof California, have invented new and useful Improvements in Nozzles, of which the following is a s ecification.

My invention re ates to a nozzle adapted to sprinkling purposes and the rime object thereof is to rovide a nozzle w ich will adjust itself to arge variations of pressure. and volume sothat it will throw a fine spray uniformly over a large area under either a light or heavy ressure.

A furt er object is to provide a nozzle which will evenly distribute a fine. spray over a large area and which will not become clogged by any foreign matter in the water fed to the same. I

A further object .is to provide a nozzle in which the wearing parts may be readily re placed by any new parts when worn out.

I accomplish these objects by means of the device described herein and illustrated in the accompanying drawings, in which Figure 1. is a front elevation of my improved -nozzle. Fig. 2. is a longitudinal Fig. 3.- is a perspective detail of the bottom end of the nozzle tube showing the notches therein. Fi 4.- is a section similar to Fig. 2 of amodi fied form of nozzle. 1

Referring to the drawings, 5 designates a base, preferably made of cast metal and provided withprojecting base lugs 6 which are adapted to impart stability in a direction at right angles to the hose, (not shown). The hose, which screws into threaded opening -7, imparts stability to the nozzle in the direc tion along the hose and thereby, with the assistance of base lugs 6, prevents it from tipping from its vertical position. 7

Base 5 is rovided with a passage 8 which leads fromose opening 7 horizontally and then upwardly to nozzle tube 9 into which the water is discharged from the hose. Tube 9 is preferably secured to base 5 b solder and is provided with a preferably cone shaped stopper. 10 having a-downwardly ex-r tendin stem 11 to the lower end of which is hooke the up er end of a rod 12. The lower end of ro 12 passes throu h a detachable bar 13 which fits across the lower end of tube 9 in notches 14 cut in the tube for that purpose. A compression spring 15 surrounds the end of rod 12 below bar 13 exert end of the rod. Spring 15 is considerably smaller in diameter than the passageway so as to leave a sufiicient space around it to provide for the passage therethroughof'foreign substances. In the normal position of stopper 10, spring 15 is in compression so as to old stopper 10 on its seat against a considerable pressure of water underneath the same. I

In Fig. 4 I have shown a modified form of nozzle in which a tension spring is utilized in place of the compression spring and ro( therefor in the first form. In this form the upppr end of the spring is secured'directly .to t e stopper and the lower end to crossbar 13.

mg a downward pressure on a washer on the In the operation of my nozzle, the water pressure in tube 9 understopper 10 will raise the same until a sufiicient opening has been created between the'tube and the stopper to allow the amount of water being supplied to the nozzle to flow out through the opening. In this manner the water is spread into a cone shaped sheet until it strikes a shoulder 16 where the sheet is broken up into a line spray, part of the water entering the out below the shoulder and rebounding therefromto strike the body; of water in the cone shaped sheet and brea it up into small particles, which rebound in every direction so that the resultant spray is evenly distributed within the radius of, operation of the nozzle.

The above explained action will take place with a large or small amount of water as the stopper will rise off of its seat on the top of the tube, just enough to allow the. amount of water fed to the nozzle to escape. The spraying action will take lace with a small amount of-water as we as with a large amount of water as the spring holds the stopper down until a sufiicient ressure has been raised inside the nozzle to orce the water into a spray. On account of the universal connection formed by the hook and. eye between rod 12 and stopper 10, it will be observed that the stopper is permitted, to be moved freely by t around it. If 1 the stop er were rigidly mounted in a transverse ireotion it is seen that especial care'would have to be taken .to make it perfectly concentric with the tube so that t e water would flow equally on all sides of it. With the presentconstruetion e water passing being The assageways of my nozzle are all sullicient y large to insure the passage therethrough of any growth whie 1 often occurs in water systems and which is the source of I constant clogging of all spraying nozzles which employ small passagewa s. Should a stone or other solid substance odge in the 1 nozzle it will be forced upwardly to the stopper when the-stopper will rise enough to ermit the escape of such solid .substance.-

Thus it will be seen that nothing except a .very large stone or the like can clog my nozzle, and any substance of that size is prevented -from entering water systems by filters or similar devices.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A sprinkler nozzle, comprising a tube adapted to beconnected at one'end' to a source of water supply, a stopper for the discharge end of said tube, and resiliently actuated means to hold said sto )per in place, said means being univcrsa y connected to said stopper.

2. A sprinkler nozzle, comprising a tube adapted to be connected at one end to a source of water supply, a conical stopper for the discharge end of said tube, said stopper being provided with an annular shoulder thereon, and resiliently actuated. means to hold said stopper in place, said means being universally COIIIIGCtCL to said stopper.

A sprinkler nozzle, comprising a tube adapted to be connected at one end to a source of. water supply, a conical stopper for the discharge end of said tube, said stopper being provided with an annular groove therein beyond the end of the tube, and a spring actuated rod mounted in said tube, said rod being universally connected to said stopper.

4. A sprinkler nozzle comprising a vertically disposed tube, a base for saidtube, said base adapted to be eonncctedto a source of water supply and being provided with a water passage leading to the base of said tube, an inverted conical stopper adapted to close the upper end of said tube, said stopper having an annular groove above the upper end of said tube, a bar across the lower end of said tube, a rod pivotally attached to said stopper and passing down-.

wardly through said bar, and a compressi n spring around said rod below said bar, said spring being adapted to force said-rod downwardly.

5. A sprinkler nozzle, comprising a tube adapted to be connected at one end to a source ol' water supply, a stopper for the discharge end ol said tube, and a spring actuated rod mounted in said tube, said rod.

being universally connected to said stopper. In witness that I claim the foregoing l have hereunto subscribed my name this 26th day ol June, 1907.
